it does the job yeah but the main problem is the finer points where

intended behavior:

• when a player is webbed/trapped and prof/sage places another web beside, the web will forcefully move character/mob. (this works already)
• when there is no one trapped and prof casts spiderweb beyond 4, 1st web cast should be deleted
• the previous web now gets deleted as the character was removed by another web, allowing to infinitely move the character/mob out of his/her will.

what is happening:

• when a player is webbed/trapped and prof/sage places another web beside, the web will forcefully move character/mob.
• the previous web persists but doesn't trap anyone anymore, and after reaching the limit of 4 webs(defined in skill_db.txt) the skill will fail until the 1st web vanishes releasing the trapped character/mob

if you'll notice the code is closely similar to ankle snare,
i built this trying to get reference from already existing skills.

any update on this mod sir?

Hi have you had a chance to fix this or maybe just the code for ground target spider web?
